Renting in Arlon for a Lux job – Confused about Garantie.be vs. Bank Guarantee?

Hi everyone,

I’ve just secured a job in Luxembourg and I’m looking to rent a flat in Arlon to commute. As an expat/newcomer, I’m trying to figure out the best way to handle the rental guarantee.

I’ve seen three main options and have a few specific questions:

Bank Blocked Account.

Garantie.be: Their site says "no funds blocked." Does this mean I literally pay 0 deposit and just a yearly fee? Is this widely accepted by landlords and agencies in the Arlon/Luxembourg province area, or do they usually demand the cash in a bank?

The Process: At what point do I bring this up? Do I tell the agency before I apply for the flat that I want to use Garantie.be, or do I wait until I have a contract draft?

If anyone has moved to Arlon for a Lux job recently, I’d love to hear how you handled the guarantor/deposit situation. Are there specific banks in Arlon that are "expat-friendly" for people working across the border?

Thanks in advance!
